Here is my entry - Taken with a standard 18-55mm stock lens on a Canon 100d, set at 18mm.  It is looking from Bunree caravan park over to Clovullin, taken on 12th October, individual exposures were 2 mins, ISO800. Not really any processing applied, the Gif was created in Photoshop.
Attached is a single shot, the animation is here but its too big even if resized to 900pixels!
High quality video here:

This one just squeezes in datewise!

Comet C/2011 L4 PANSTARRS near Messier 31.  Taken on 3rd April from a dark location with a clear low northern horizon on a gated road near Redesmouth, Northumberland.  The comet was then circumpolar, but by full dark (10 pm) was never above 11 degrees altitude and rapidly fell to 6. So even with a clear sky was in thick air.

The tail was large and diffuse, stretching right across M31. Modded Canon 350D with 200 mm (old style M42 thread) lens at f8 and ISO 800. 8 x 5 minute subs on my EQ3-2 mount, guided in RA only (I had a good Polar alignment) with a Lodestar and a 300 mm mirror lens. Stacked with Deep Sky Stacker, final processing in Photoshop.  

Although this was guided, it was a relatively 'slow' lens and an 8 year old camera - more modern DSLRs are more sensitive and less 'noisy'.  So I believe that the SkyTracker, which almost certainly has a lower Periodic Error than my Meade DS motor driven 10 year old EQ3-2 mount, would have been capable of producing this image unguided with a faster lens and higher ISO setting on a modern DSLR, using 1 or 2 minute subs.

Amusingly one of my subs was ruined by what I assume was a passing Police car. Must have spotted my red head torch, stopped on the road outside the gate and pointed a spotlight straight up the lens! A frantic cry of 'Put that light out' was too late. They just drove on, but I have a nice white sub!

THIS IS NOT AN ENTRY

Unfortunately it was taken prior to the starting date of the competition.  And this is the large size image. But I've posted it because it shows just what would be possible with the Skytracker when travelling abroad.  Taken at the Cradle Mountain area of Tasmania on 15th February this year, modded Canon 350 D, 800 ISO with Tamron 17-50 mm f2.8 zoom lens at 17 mm and f5.6 under very dark clear skies - at least until cloud appeared out of nowhere towards the end of the second sub!  Just 2 x 10 minute subs unguided with the camera on my EQ3-2 mount with Meade DS drives - certainly worse periodic error than the SkyTracker.

I've had that mount for several years and it has travelled extensively with me.  But it weighs 10Kg with the balance weight - doesn't half cut into the airline allowance!  So even if your entry is not the winner, save up your pennies  :thumbup:

Cheers,

Peter.

Camera used: Modified Canon 40D with an Astronomik 12nm Ha clip-in filter
Lens used: Canon 200mm f2.8 L lens

Taken just before midnight on 29th November 2013 using QHY8 plus Vivitar 28-70 zoom lens with Itorex semi Fish Eye adaptor. Only 11x1 min exposures stacked in DSS & lightly processed in Photoshop Elements. I wasn't able to include LP Filter in imaging train so original image very orange. Probably overcorrected but to me this seemed to be the most striking and shows what can be seen even from a back garden in light polluted suburbia (Sutton).

In the UK the Milky Way is at its best in late August when the skies are dark and part of Sagittarius is visible. But later in the year it can still put up a wonderful show, and although I am on the edge of the Hexham Northumberland 'light dome' a clear night gives me a good view from my back garden, particularly looking West and South over the North Pennines. This image was taken early in the evening of 22nd November 2013 before the Moon rose. It consists of a two frame mosaic, the top third or so being added to a full frame lower section to include all of Cygnus.  A pillar of smoke and sparks rising from my Observatory  ;)

Canon 350D modded for Hydrogen alpha with Tamron 17-50 f2.8 lens at 17 mm and f5.6, ISO 800.  Lower section 6 x 5 minutes, upper 5 x 5 minutes all unguided on my EQ3-2 mount. With the mount tracking the sky, the horizon was very blurred, so I later patched in a static shot clearly showing my Observatory and skyline. This is correctly positioned - a crop from the original stacked image is here http://www.madpc.co.uk/~peterv/astroplover/350Dpics/Medium/Novmilkyskyline.jpg

Processed with Deep Sky Stacker and Photoshop, brighter stars slightly tweaked with Star Spikes Pro to improve the already existing starburst effects from the lens diaphragm.

The night of 5th December 2013 was set to be clear all night - one of the very few this season, so I set to with my QSI camera to image three iconic objects in the same field of view. Originally outside on my EQ3-2 mount, but the weather was still very blustery after the severe gales of the morning (which cut off our electricity for 8 hours - fortunately it was back on in the evening!) so I had to admit defeat and move the camera onto my Observatory mount (Hexham, Northumberland).  Which meant with the wide field of view I had to move the dome every 25 minutes or so!  QSI 683 with Tamron 17-50 f2.8 zoom lens at 35 mm and f5.6

Luminance 11 x 10 minutes, RGB each 4 x 10 minutes binned 1x1. I also took 6 x 15 minutes Hydrogen-alpha to pick out detail of the California nebula. This was then used for both luminance and colour of the nebula. The brighter stars were already showing 'starburst' effects from the lens diaphragm, so I lightly enhanced them further using Star Spikes Pro.

The 2013 Perseids didn't start too well, but I persisted in imaging through scattered cloud. This fireball (which had a persistent train) was the result. From my back garden in Milton Keynes.

Milton Keynes AS have an annual dark-sky weekend, usually near Craven Arms in Shropshire. I was imaging the summer triangle region when this bright (-2) meteor crossed the frame. A nice case of serendipity.
